Question

是否有人为ajax源成功修改了上述小部件？我已经能够进行修改，除了突出显示选项的搜索词外，它工作正常。更具体地说，下面的代码。

var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
                        response( select.children( "option" ).map(function() {
                            var text = $( this ).text();
                            if ( this.value && ( !request.term || matcher.test(text) ) )
                                return {
                                    label: text.replace(
                                        new RegExp(
                                            "(?![^&;]+;)(?!<[^<>]*)(" +
                                            $.ui.autocomplete.escapeRegex(request.term) +
                                            ")(?![^<>]*>)(?![^&;]+;)", "gi"
                                        ), "<strong>$1</strong>" ),
                                    value: text,
                                    option: this
                                };
                        }) );

这是我对小部件的修改：

(function ($) {
    $.widget("ui.Clients", {
        _create: function () {
            var self = this,
                select = this.element.hide(),
                selected = select.children(":selected"),
                value = selected.val() ? selected.text() : "";
            var input = this.input = $("<input>")
                .insertAfter(select)
                .val(value)
                .autocomplete({
                    delay: 0,
                    minLength: 0,
                    source: function (request, response) {
                        $.ajax({
                            url: "/Controller/Action", type: "POST", dataType: "json",
                            data: { searchText: request.term },
                            success: function (data) {
                                response($.map(data, function (item) {
                                    return {
                                        value: item.ClientName,
                                        id: item.ClientId
                                    }
                                }))
                            }
                        })
                    },

任何人都可以协助将该功能集成到我的ajax调用中吗？

小部件期望响应的返回值中有一个label属性。 label属性是自动完成窗口中显示的内容。如果您没有指定label属性，那么它只是value属性。因此，您需要做的就是更改label属性的原始值并用item.ClientName替换文本

(function ($) {
    $.widget("ui.Clients", {
        _create: function () {
            var self = this,
                select = this.element.hide(),
                selected = select.children(":selected"),
                value = selected.val() ? selected.text() : "";
            var input = this.input = $("<input>")
                .insertAfter(select)
                .val(value)
                .autocomplete({
                    delay: 0,
                    minLength: 0,
                    source: function (request, response) {
                        $.ajax({
                            url: "/Controller/Action", type: "POST", dataType: "json",
                            data: { searchText: request.term },
                            success: function (data) {
                                response($.map(data, function (item) {
                                    return {
                                        value: item.ClientName,
                                        id: item.ClientId,
                                        label: item.ClientName.replace(
                                                new RegExp(
                                                    "(?![^&;]+;)(?!<[^<>]*)(" +
                                                    $.ui.autocomplete.escapeRegex(request.term) +
                                                    ")(?![^<>]*>)(?![^&;]+;)", "gi"
                                                ), "<strong>$1</strong>" ),
                                    }
                                }))
                            }
                        })
                    },
